To view processes nice value with ps command in user-defined format (here the NI the column shows the niceness of processes). Alternatively, you can use top or htop utilities to view Linux processes nice values as shown.

What is Ni in top command?

Originally Answered: What is the difference between the NI and PR values in the top(1) command’s output? NI is the nice value, which is a user-space concept. PR is the process’s actual priority, as viewed by the Linux kernel. For normal processes, the kernel priority is simply +20 from the nice value.

What is nice command?

Nice is a command in Unix and Linux operating systems that allows for the adjustment of the “Niceness” value of processes. Adjusting the “niceness” value of processes allows for setting an advised CPU priority that the kernel’s scheduler will use to determine which processes get more or less CPU time.

What is PR in top?

PR is the process’s actual priority, as viewed by the Linux kernel. For normal processes, the kernel priority is simply +20 from the nice value. Thus a process with the neutral nice value of zero has a kernel priority of 20.

Which type of user can give lower nice value?

These guidelines are called niceness or nice value. The Linux niceness scale goes from -20 to 19. The lower the number the more priority that task gets. If the niceness value is high number like 19 the task will be set to the lowest priority and the CPU will process it whenever it gets a chance.
